ROUNDING AND CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 595,764, dated December 21, 1897.

Application filed January 31, 1895. Serial No. 536,809. (No ma i.)

To all whom it may concern.-

Be it known that I, EDWARD M. COLE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shoe Machinery, of which the following is a specification.

My invention relates to rounding and chairneling machines of the class in ordinary use, and has for its object the addition of certain devices for giving the operator more perfect control of the location at which the cutting is done by the rounding and channeling tools.

In the accompanying drawings, Figure 1 is a side elevation showing my improvements and as much of a rounding and channeling machine as is necessary to illustrate their relationship to previous devices. Fig. 2 is a similar view showing the parts in an inter- Fig. 3 is a front elevation showing the parts adjacent to the roundingtool. Fig. I is a front elevation of some of the operating and controlling parts at the rear. Figs. 5 and 6 show the extreme positions of the adjustable gage in contradistinct-ion to the intermediate position shown in Fig. 2.

In Fig. 1 the rounding-tool and the throat plate through which it works are shown in their relative positions; but in Fig. 2 these parts have been omitted for the purpose of permitting a view of the stationary gage (which is immediately behind the throatplate) and its relationship to the adjust-able gage.

In the said drawings, 1 represents parts of the frame of an ordinary rounding and channeling machine, on one portion of which is a slide 2, that is connected by means of the link 3 to the arm 4 on the shaft 5. On the other end of the shaft 5 is another arm 6, to which is pivoted a link 7, that'extends downward and is connected to a treadle (not shown) within reach of the operator. On the top of the box 8, which forms part of the frame 1, is a threaded stud 9, that is provided with nuts 10 and 11, adjustable along the same. The stud 9 passes through a hole in the arm 6 and the nuts 10 and 11 and serves to regulate the length of movement of the said arm when operated by the treadle through the link 7. On the side of the box 8 is pivoted to swing laterally a lever 12, on the upper end of which is a block 13, that is vertically adjustable by means of the screws 14, which pass through slots 15 in said block. On one side of the block 13 is alug 16, which engages the lever 6 and serves to stop and hold the said lever from upward movement. The lower end of the lever 12 extends downward to a point convenient for the operator to press it laterally with his knee and thus release the lug 16 from the lever 6.

It will be observed that the amplitude of the stroke of the lever 6 when operated by a treadle through the link 7 is controlled by the location of the nuts 10 and 11 on the stud 9, and consequently that the stroke of the arm 4 and the length of the reciprocation of the slide 2 are controlled by the same means. The slide 2, which is moved forward by pressing the foot upon the treadle, may be returned to its normal position by any convenient means, as the spring 17, one end of which is connected to the pin 18 in the frame 1 and the other end to the' piece 19 on the slide 2.

At the front of the machine, A represents the rounding knife; B, the throat plate through which it works; 0, the stationary gage; D, the channeling-knife, and S and U portions of the sole and upper, respectively, of a shoe that is being operated upon by the machine. In ordinary practice the location of the cuts made by the knives A and D is determined by keeping the shoe pressed up against the stationary gage O. In my improved machine the location of these cuts is determined partly by the stationary gage and partly by an adjustable gage 20, that is mounted over the stationary gage and may be advanced and retracted at will by the operator. The object of this is generally to enable the operator to make the edge of the sole wider at some places than at others, and more particularly to widen the edge on the fore part along the ball portion, so that the edge of the sole, when viewed from above, will more nearly correspond to the general outline of the shoe, and consequently have a better appearance.

and adjacent to the toe.

operator presses his foot upon the treadle connected to the link 7 the lever 6 will be forced down into contact with the nuts 11, as shown in Fig. 1, and that the gage 20 will assume the position shown in Fig. 6. This forces the shoe away from the cutting-tools A and D, and consequently produces awider edge upon that portion of the sole which is then being operated upon and properly positions the channel with reference to such extended edge. When he releases his foot from the treadle, the spring 17 retracts the gage 20 until the lever 6 is stopped by contact with the lug 16 on the adjustable block 13. This leaves the gage 20 in the position shown in Fig. 2 and produces the medium or intermediate width of sole. When he presses his knee against the lever 12 to cause the lug 16 to release the lever 6, the gage 20 is further retracted into the position shown in Fig. 5, thus permitting the shoe to come into contact with the stationary gage 0, thereby causing the narrowest width of sole to be produced. In practice the narrowest part of the edge of the sole will usually be at the shank portion, the widest part at the ball portions at either side, and the intermediate width at It is therefore to be seen that the fixed guide controls the shoe along the shank portions and the movable guide around the fore part. My invention is, however, susceptible of other uses, and the operation of the fixed and movable guides may be varied to suit. such uses.

lVhat I claim is 1. A fixed guiding device for controlling the location of a shoe While being operated upon by rounding and channeling tools, an adjustable guiding device adapted to interpose so as to force the shoe farther from said tools, and means for advancing and retracting said adjustable guiding device while the tools are in operation.

2. A fixed guiding device for controlling the inward location of a shoe operated upon by rounding and channeling tools, an adjustable guiding device for pushing the shoe outward, stops for limiting the movement of the adjustable guiding device, and means for shifting the position of said adjustable guiding device.

3. In a rounding and channeling machine, a stationar gage, an adjustable gage, mounted on the top of said stationary gage, and devices for advancing and retracting said adjustable gage.

4. A fixed guiding device and an adjustable guiding device, means for advancing and retracting the latter, stops for limiting its movement, and a catch for holding it at a position intermediate its extremes.

5. In a rounding and channeling machine, an adjustable guiding device, means for advancing and retracting said device, stops for limiting its movement, a catch for holding it at intermediate position, and means for adjusting said catch to different intermediate positions.

6. In a rounding and channeling machine, an adjustable guiding device and means for moving it, adjustable stops for limiting such movement, a device for holding said guiding device at an intermediate position, means for adjusting said holding device, and a lever for releasing said holding device.

7. A stationary gage, an adjustable gage movable on the top thereof, operating devices for reciprocating said adjustable gage, and adjustable stops for regulating the movement of said operating devices.

8. In a machinefor operation upon the soles of boots and shoes, two independent guides, one Working along the shank portion and the other around the fore part.

9. In a rough rounding and channeling machine the combination with the roughrounding knife, of a fixed gage, a movable gage mounted adjacent thereto and movable transversely to the direction of the feed, and mechanism for actuating the movable gage during the operation of the machine.
